Merge #7824
7824: feat: add type ascription r=matklad a=conradludgate Based on this conversation: https://twitter.com/rust_analyzer/status/1366092401278922757 Built off of `add_turbo_fish`, finds the current `let` statement, checks if it has type/turbofish already and checks if the rhs function is generic. There's one case I couldn't figure out how to implement that would be nice: ```rust #[test] fn add_type_ascription_function_result() { check_assist( add_type_ascription, r#" fn make<T>() -> Result<T, &'static str> {} fn main() { let x = make()$0; } "#, r#" fn make<T>() -> Result<T, &'static str> {} fn main() { let x: Result<${0:_}, &'static str> = make(); } "#, ); } ``` The `Function::ret_type` fn wasn't returning anything much useful so I'm not sure how to identity such scenarios just yet Co-authored-by: Conrad Ludgate <[email protected]>
